When developing a new exhibition most science centres rely on scientists and scientific institutions. But what do we expect from them? Expertise and skill, validation and acknowledgment, creativity and inspiration, or even money? In this session we will present different collaboration models between science centres and the scientific community and explore their pros and cons. What happens if the science centre doesn’t agree with the scientist’s idea, or vice-verse? How far should scientists take part in the process? If companies and sponsors are part of the scientific committee, does this raise questions about neutrality?
